This invention relates to Jfountain pens and particularly to an improved lever construction and mounting; tor pens ot the class under consideration employing' compressible walls or sacks compressed by said lever through a bar positioned between the le fer and the sach; and the object oi the inventionis to provide ineens 'for pivotally mounting` a lever in connection with the ypen body and tensional inca-ns engaging said lever for retainingv the same in closed or inoperative position and out oli operative connection with the `bar einployed; a iurtlier object being` to provide the bore ot the pen body with an annular groove or recess in which a coil springl adapted to be' mounted -tor engagementwitha notch in said lever tor retaining the' saine in position and against accidental displacement; and with these andother objects in view', the invention consists in a'de'vice ot'l the class and for the purpose: specilied which is simple in construction, ellicient infuse and' -which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the iiollowing specification, ot which the accompanying drawing `forms a part7 in which the separate parts of myimprovement are designated by suitable reference characters in cachot the viewsj and in which F ig. l is a partial7 longitudinal, sectional view through a pen body illustrating my im proved lever construction n'iounted in connection therewith. Y f

F ig. 2 is a plan view oit a part ot the construction shown in Fig. 1.

Fie. 3 is a section on tne line SW3 of Fie.

1 and on an enlarged scale; and

F ig. is a perspective detail view o'l tlie lever which l employ.

ln Fig. l oit the drawing, l have indicated at 10 the barrel lof a fountain pen which is closed at one end as seen at 11, and the pen point tip portion 12 is mounted in connection with the open end thereof and carries the usual flexible or compressible well sack i3 which extends into the barel 10 of the pen.

l At 14, l have indicated a bar which may be of any convention form, which lies upon one tace oi.l and extends longitudinally of the sack 13. In the construction shown, the bar 14; is oit channel formation in cross section as clearly seen in Fig.. 3 of the drawing.

ln the barrel or body 10 of the pen substantially Centrally thereof is an elongated aperture 15 in which is mounted a lever 16 pivoted to a split wall ring 17. The rinfr is retained in position by engagenientwith an annular groove 18 in the bore of the body 10. The lever 16 is ot lchannel 'formation in cross section. the channel being directed inwardly with reference to the bore oit the body l() when the `lever is in use. @ne end 19 ot lthe chan-- nel is reduced and the side langes rounded for engagement with the bar 14; inl the oper-r ation oi compressing the sack 13, while atthe other end o'l' said lever the flanges are cut baclrwardly to torni notches 20 therein and to provide projectinglip or linger pieceQl whereby the operation of the lever is `facilitated. 'lliat part ot the barrel or body 10 adjacent Vthe iii'iger piece 21 is recessed as seen at Q2 to permit olE the insertion of the nail ot a linger beneath the linger piece 21 to vperniit the lever to be raised into vertical or substantially vertical position in the depression koit the bar l/l to con'ipress the sack' 13.

Adjacent the recess 22 in the body 10, the bore thereoi'isr provided with a comparatively vide annular recess 23 in which is mounted a light coil spring :9A in such position and relation with the lever 16 as to engage the notches 20 in the `side flanges ot saidlever to retain the lever in the position shown in F ig. 1 oft' the drawing against accidental displacement, and further to support said lever in parallel relation with reference te tlie outer `tace el the barrel er body l0 of the pen, and with the ends 19 olf the lever out ofengage ment with the bar lll as clearly seen in Fig. 1

it the drawing.`

lt will be understood that my invention is not'liinited to the use oic a bar loit any specic iorin and construction nor am l necessarily limited to the specilic .means herein shown and described lor retaining the lever in position, and various other changes in and modi` tications oi the construction herein shown and described may be inade within the scope of the appended claims without departing' from the spirit of my invention or sacrilicingr its advantages.

Having fully described my invention, what l claim as new and desire to secure by Lett-ers Patent, is l 1. In a pen of the class-described, a lever pivotally mountedin the body of the pen, a linger piece atene end of the lever whereby the other end oi said lever may be moved into the body of the pen, and means adjacent the finger piece end oi the lever and cooperatinfn` therewith tor retaining said lever in inoption against displaceinent, and said means comprising a spiral spring mounted in an annular groove in the bore of the pen body and adapted to enga-ge a notched portion on said lever.

3. In a pen employing a pen body, a eom pressible Well within said body and a bar eX- tending longitudinally of said Well, a lever pivotally mounted in an aperture in the body of the pen, said lever when in horizontal position being out of engagement with said bar, means for retaining said lever in such posi tion against displacement, said means cornprising a spiral spring mounted in an annular groovein the bore of the pen body and adapted to engage a notched portion on said lever and the notched end portion of the lever being provided with a finger piece.

4. In a fountain pen of the class described, the bore of the body of which is provided With a comparatively' Wide annular groove, a coil spring mounted 'in said groove, the well of the pen body having an elongated aperture extending longitudinally thereof and opening into said annular groove, and a lever pivotally mounted in the aperture of the pen body and one end of said lever being fashioned to engage said coil spring to retain said lever in parallel relation With reference to the well of the pen body. e

5. In a self-filling fountain pen, a lever piv otally mounted in the body ofthe pen', a bar mounted in the pen and adapted to be actuated by said lever, said lever comprising an elongated strip of metal of channel formation in cross section7 the side Walls at one end of the lever being eut away to form a projecting' Y finger piece, and notches in the ends of said side Walls and directed toward said finger piece, the bore of the pen body having a coinparatively Wide annular groove adjacent the notch portion of the lever, and a comparativa ly light coil spring adapted to be supported in said groove and to engage the notches in the end of said lever to retainsaid lever in horizontal ostion with reference to the Wall of the pen body and out of enga-gement with said bar.

In testimony that I claim the foregoing as my invention I have signed my name this 1st day of March, 1926.
